How do you apply parylene to a printed circuit board?

Parylene is applied through a specialised vapour deposition process at ambient temperature. Parylene polymer deposition occurs at a molecular level, where the coating literally grows one molecule at a time on the substrate surface, assuring entirely conformal and uniform layers of parylene conformal coating are applied.

The process begins with the raw, granular material called the dimer which is heated under vacuum. The dimer is then reduced to a gaseous state in the vaporising chamber. The vapour is next drawn into the furnace and heated to very high temperatures (pyrolised) to allow for sublimation and the splitting of the molecule to a monomer. The gas is finally drawn into the room temperature deposition chamber, where the monomer gas deposits on all surfaces as a thin, transparent polymer film and the result is a parylene conformal coating uniformly deposited on the product.

Because the Parylene is applied as a gas, the conformal coating easily penetrates everywhere on components, providing complete and uniform coverage. Literally a conformal coating. . While Parylene coatings can range in thickness from hundreds of angstroms to several mils, a typical thickness is in the microns range.
